What are the key features of TFC-109-02-FM-D?
- 18-position dual-row board stacking connector with 0.050" (1.27 mm) pitch for compact high-density PCB-to-PCB connections
- Tiger Eye cost-effective design reduces connector acquisition cost while maintaining SAMTEC's standard contact quality and dimensional accuracy
- SMT termination style enables automated pick-and-place assembly and compatibility with standard reflow soldering processes
What is TFC-109-02-FM-D used for?
The TFC-109-02-FM-D serves as a compact mezzanine connector in small-form-factor embedded systems, IoT sensor boards, and portable instrumentation where 18 signals need to bridge two stacked PCBs. Its 0.050" pitch minimises connector footprint while the dual-row layout supports mixed signal and low-current power lines. The Tiger Eye cost-effective construction makes it attractive for high-volume consumer and industrial designs that demand reliable interconnection without premium pricing.

Frequently Asked Questions
How does the TFC-109-02-FM-D's 18-position count and 0.050" pitch compare to standard 2.54 mm pitch connectors in terms of board space?
The TFC-109-02-FM-D occupies only about 11.4 mm of board length at 0.050" (1.27 mm) pitch versus roughly 23 mm for an equivalent 18-position 2.54 mm pitch connector. This nearly 50% reduction in connector length is critical when routing sensor interfaces or SPI/I2C buses between stacked boards in compact IoT or wearable devices with tight PCB area budgets.
In which low-to-mid-complexity embedded designs is the TFC-109-02-FM-D a suitable mezzanine connector?
This 18-position connector suits designs requiring a single byte-wide bus plus control lines, such as SPI flash memory daughter cards, LCD display modules, or sensor fusion boards stacked onto a main processor PCB. Its 18 pins can carry a 16-bit parallel data bus with 2 chip-select or interrupt lines, covering common microcontroller peripheral bus widths at 3.3 V or 5 V logic levels.
What makes the Tiger Eye TFC-109-02-FM-D a lower-cost alternative to standard SAMTEC terminal strips without sacrificing reliability?
The Tiger Eye series reduces material and processing costs through optimised contact stamping geometry while retaining SAMTEC's baseline dimensional tolerances, ensuring mating compatibility with standard 0.050" pitch sockets. Contact resistance remains below 20 mΩ and the tin-nickel termination withstands standard reflow profiles up to 260 degrees C, making it a drop-in cost reduction for price-sensitive production programs.
